What is swCFMExtMgmtLockLevel?

This is the lock-function counterpart to swCFMExtMgmtAISLevel, specifying which client-side maintenance domain level receives the LCK PDUs signaling that this segment is intentionally out of service for maintenance. It matters for the same level-ordering reason as the AIS level object; the lock signal needs to reach the correct client-level domain so that tier's monitoring correctly interprets the outage as planned rather than as an unexplained fault. An operator performing maintenance visible to a customer's level-5 domain would set this to level 5, matching whatever level swCFMExtMgmtAISLevel would target for the same segment's fault suppression.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.12.86.1.1.1.7
snmpwalk -v2c -c public <target> CFMEXTENSION-MIB::swCFMExtMgmtLockLevel

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.171.12.86.1.1.1.7.1
snmpget -v2c -c public <target> CFMEXTENSION-MIB::swCFMExtMgmtLockLevel.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.171.12.86.1.1.1.7.1 s <value>
